Just curious were you on the dining plan? We have had to order off the adult menu occasionally when there were no safe kids options, but nobody ever gave us a hard time about it. Usually, we are charged for the adult meal, but once in a while they will charge us a kid's price.
Once in a blue moon I've had a chef who just appears annoyed at having to deal with us, but the vast majority have been great. Sorry you experienced some of the not so great ones.
Yes, we were on the dining plan. I even offered to pay the difference but he just said "we can't do it." and walked off in a snit. I was frankly shocked, as most places were fabulous with it. That said, we were very unimpressed with our whole experience there that night- we had CM's with name tags on sitting down and drinking at tables during their shift- they were joining groups of friends for drinks when they were clearly "on duty". This was two years ago in June.
